What happened this week in One Chicago history? Here are the moments from Chicago Fire, Chicago PD and Chicago Med past in the week of March 12-18.

While we enjoy the current week in One Chicago, we’re also looking back into what happened this week in One Chicago history.

These are the important dates in Chicago Fire, Chicago Med, Chicago PD and Chicago Justice past that you might remember. And if you don’t, we’ve got a refresher.

This week involved several premieres, one big reveal and a few repeats along the way.

Here’s what happened this week in One Chicago history:

More from One Chicago Center

March 12, 2014: The Chicago PD season 1 episode “Different Mistakes” airs.

Four years ago Internal Affairs wasn’t letting up on Hank Voight (Jason Beghe) and assigned him a new handler, Stillwell (guest star Ian Bohen), who made his presence known to everyone in Intelligence. Voight seemed to confirm Stillwell’s suspicions when, at the end of the episode, he was arrested in a sting after taking cash from gang leader (and CI) Maurice Owens (recurring guest star David Aron Damane), in exchange for promising protection for a drug shipment.

Making things even more complicated, Voight’s former partner Jimmy Shi (guest star Mark Dacascos) surfaced in the middle of Intelligence’s own sting operation but not in a good way. It appeared that being undercover for 11 years had led to Shi and his team flipping sides, but after another similar robbery and murder was committed it became clear that they were being framed.

March 12, 2017: The Chicago Justice season 1 episode “Judge Not” airs.

Judgment hung heavily in the air of the State’s Attorney’s Office last year when prominent Judge Kinzie (guest star Douglas Sills) was murdered after leaving a bar with ASA Anna Valdez (Monica Barbaro). Valdez was the target of many of the same assumptions that assault victims face from the justice system and society even though her relationship with the judge was irrelevant to the case.

A complicated investigation finally led to the discovery that the judge was murdered by the jealous and controlling ex-husband of a rape victim whose assailant’s trial was handled by Kinzie. And although we never explicitly learned what Anna’s connection was to the victim, at least justice was gotten for her fallen friend.

March 13, 2013: The Chicago Fire season 1 episode “It Ain’t Easy” repeats.

In this episode that had originally aired in Dec. 2012, Chief Boden (Eamonn Walker) refused to give up on a teenager suspected of the arson that led to Jose Vargas (guest star Mo Gallini) being forced on disability. As Boden looked into Ernie’s (guest star Cody Sullivan) life, Vargas kept showing up at the firehouse, even after his extensive lung damage made it clear he would never return to the job.

Meanwhile, Kelly Severide (Taylor Kinney) rescued a woman from a crashed car surrounded by live electrical wires. That was his introduction to Renee Royce (recurring guest star Sarah Shahi), who would be Severide’s first serious love interest on Chicago Fire. We’ve since learned she’ll be resurfacing later this season, so how will he handle that five years later?

March 15, 2017: The Chicago PD season 4 episode “You Wish” repeats.

In this installment from Jan. 2017, a sex offender’s body was found mutilated and Intelligence was tasked with determining if he was the victim of a hate crime, sexual assault or self-mutilation gone awry. But the team found itself up against a private police force that was responsible for the murder. Did the end of removing a known offender justify the means and how different was the leader of this band of vigilantes from Voight and his questionable approaches?

Plus, this was the episode where Erin Lindsay (Sophia Bush) found out that Jay Halstead (Jesse Lee Soffer) had gone behind her back and confirmed that Jimmy Sanguinetti was not her father after all. Well, somebody would end up sleeping on the couch for that. Plus, this happened:

March 16, 2017: The Chicago Med season 2 episode “Monday Mourning” airs.

It was this week last year when Chicago Med finally told us which recurring character it was killing off: well-meaning but troubled ED doctor Jason Wheeler. Though many fans had guessed Wheeler was the victim well before this episode premiered, audiences were still affected when the episode opened with him committing suicide by stepping off a hospital balcony.

The rest of the hour involved the team struggling to cope with his demise, while also trying to save their patients of the week. It was particularly hard for Dr. Sarah Reese (Rachel DiPillo), who felt she had missed Wheeler’s cry for help. But really, there was no one to blame, and everyone in the One Chicago fandom was touched by this episode.

March 17, 2015: The Chicago Fire season 3 episode “Forgiving, Relentless, Unconditional” airs.

Christopher Herrmann (David Eigenberg) took center stage in this episode when he went the extra mile to rescue a toddler trapped in a fire. When it became clear the fire was not an accident, the fiercely protective father side of Herrmann went into overdrive, and he made it his mission to mete out some street justice to the boy’s negligent father.

This was also the episode that started the exit storyline for Peter Mills (Charlie Barnett). Mills was faced with a difficult choice between family and career when his sister wanted him to relocate to North Carolina to start a new restaurant with her at the same time he found out that he was medically cleared to return to the squad.

March 18, 2014: The Chicago Fire season 2 episode “When Things Got Rough” airs.

Speaking of Severide, his past struggle with addiction took a front seat in this episode from four years ago when he recognized similar signs in a former firefighter the squad rescued in a car accident. Although his efforts to help seemed to be going well, the man suffered a relapse after visiting Firehouse 51 and Severide wasn’t able to get him back on the wagon.

Also in this episode, Firehouse 51 found itself the defendant in a wrongful death lawsuit after the wife of the man who died in the episode’s house fire lashed out in anger over her husband’s loss. The emotional testimony that Matthew Casey (Jesse Spencer) gave during his deposition, describing how the man died a hero by protecting his children from the fire and ultimately saving their lives at the cost of his own, enabled his wife to understand and prompted her to drop the lawsuit.
